Disney World starts decorating for Christmas in early November, and the decorations are usually completed by mid-November. This allows plenty of time for guests to enjoy the festive atmosphere and get in the holiday spirit. The parks are decorated with traditional Christmas decorations, including trees, lights, wreaths, and garlands. There are also a variety of special events and activities that celebrate the holiday season, such as the Christmas parade, the Mickey's Very Merry Christmas Party, and holiday-themed shows and attractions.
